I want to compare the capture quality of my Geforcefx 5900 with my Hauppauge tuner card. Getting right to the point, I cannot get any video to show up using my video in on my graphics card. I have installed the wdm drivers from my geforce cd then installed ulead video studio 7 that came with my card. When I go into ulead the only source I can choose is my Hauppauge drivers. My graphics card does not show up as a choice. When I unhook the s-video from my graphics card and put it back into my tv tuner everything works. So shouldn't my graphics card work too? Anybody have any ideas on what I need to do? Any help would be appreciated.
